Specification of Letters Eatcnt.

Patented Sept. '2, 1915.

Application filed March 18, 1913. Serial No. 755,104.

To all whom it may concern:

Be it known that 1, PAUL A. DRUoKLInB, a citizen of the United States,and a resident of New York, county of New York, and

tate of New York, and whose post-office address is let Park Place, NewYork city, county of New York, and State oi New York, pray that LettersPatent may be granted to me for Improvements in Machines for FinishingCigarette-Seams, of which the following is a specification.

My present invention relates to certain novel constructions to be usedfor the purpose of finishing the scam in a pasted cigarette rod.

The particular type of device to which my present invention is directedembodies the idea of a presser finger or blade, preferably, having acontact surface where it bears upon the seam,,o't' a little more thanthe width of the seam, so that the pressure exerted by the blade on theseam will be substantially coextensive with its width, and additionallywherein the pressure of the blade radually increases the movement of thecigarette rod under the presser finger bar progresses. Such a type ofscam finishing device is shown and described in the application forLetters Patent which 1 filed jointly with Daniel Hemrningon the 31st dayof May, 1912, Ser. No. 700,609. It is to a device of this class which mypresent invention relates, and it consists in novel structures orembodiments of the underlying ideas set forth in said application, whichwill be hereinafter more fully described, and finally set forth in theclaims appended hereto.

In the drawing forming part of this application, Figure 1 is aperspective view of a portion of a cigarette making machine, and a likefront view of my improved seaming device secured in operative positionthereto. F ig. 2 is a like view taken at the rear of Fig. 1. Fig. 3 isan enlarged sectional elevation, the section being taken substantiallyon the line 3-3 of Fig. 1, looking in the clirection of the arrows.

Fig. 11 is atransverse sectional elevation on the plane of the line 11-11 of Fig. 9,looking in the direction of thearrows; and Fig. 12 is a perspectiveview, showing a further modification.

Like reference characters indicate similar parts throughout the severalviews.

The embodiments of my invent-ion, as shown herein, are adapted to aconventionally constructed cigarette making machine.

They, however, may be adapted to machines specially designed, withoutmuch diiliculty. So far as my present improvements are concerned, theonly essential parts of the cigarette making machine that it isnecessary to describe here is the conveyor tape which conveys thecigarette rodto the seaming and fii'iishing device, a tube through whichthe tape passes after or during the time the lap of the seam has beenformed and pasted, means for propelling the tape and cigarette rod, andsuitable supports for the said devices. I shall describe only that muchof the cigarette making machine which is em'- braced in the foregoingstatement, as I deem that to be sul'iicient for the purpose ofillustrating the application of my invention.

At 1 is a portion of the bed or" a cigarette making machine. At 2 is aplate constituting the terminal portion of the grooves through which theconveyor or propelling tape and the cigarette rod move. A thumb screw 2may be used for detachably seaming the parts together. In devices ofthis kind, there is usually in advance of the terminal of the grooves,means for lapping and pasting the edges of the paper surrounding thetobacco core, and for guiding the pasted rod and tape through theterminal block and to the ironing or finishing means.

The cigarette rod, comprises the tobacco filler 3 and the paper covering4: having the overlapped edges 5 and 6.

At 7 is the propelling wheel about which the conveyor tape 8 passes andwhich acts as the means for propelling the tape and cigarette rodthrough the machine. T he edges of the tape, when embracing the cigarette rod do not meet, so that when the rod and encircling tape passthe pasting and finishing devices access to the seam of the rod may behad between their edges.

' clusive.

The foregoing are conventional parts, and may be constructed as shown,or modified to suit the particular requirements.

1 shall first describe the embodiment of my invention as shown in .Figs.1 to 4' inmovement of the cigarette rod. The plate 9.

has arms 10 and 11 in which are included upright sections 12, 13 so asto elevate the parts supported by the frame over and above the plane ofthe cigarette rod. The arm 11 is provided with anupright section 14:having a lug 15, and the arm 10 with an upright head 16. At 17 is ablock recessed to bear against the rear and side ofv the section 1 1,and provided with a slot 18, through which projects a set screw 19, bymeansof which the block may be adjusted up and down relatively to thearm 1 1; and at 20 there is another set screw or stop, which is threadedthrough the lug 15 and which may be caused to bear against the top ofthe block 17 to limit the upward movement of the same and set it at thedesired relative height, The head 16 is doubly bored as at 21 22, thebore 21 being interiorly threaded and provided with a set screw 23against the bottom of which bears a spiral spring 2 1, which latterpasses down into the bo e The head 16 is also provided with a slot whichis formed in its bottom and which opens into the bore 22 and in linewith both bores 21 and 22. At 26 is the finishing element of the device,comprising what I call a presser blade. By reference to Fig. 4 it willbe seen that this blade has greater depth than width and that theoperative or finishing surface or edge 27 is substantially coextensivein width with the width of the seam, so that, as explained in mybeforementioned application, the pressure exerted by the blade upon theseam, and its bearing thereon, as shown in Fig. 41, will beapproximately that of the lateral dimensions of the seam itself, leavingthe balance of the rod undisturbed. That is, the ironing or finishingfunction of theblade is confined to substantially the lateral limits ofthe. seam itself, instead of putting the entire rod under pressure. Ofcourse, it is only essential, so far as this feature of my invention isconcerned, that the contact or operative surface 27 of the blade hasthis characteristic, the rest of the blade being constructed as desired,my present invention relating only to means for supporting and operatingit. The blade 26 is supported so that its heel 28 (Fig. 1) will lie in ahigher plane than the toe portion 29, the heel being located adf jacentthe point of exit of the pasted rod from the guiding tube or channel ithe in- At 9 is a plate provided with screw f holes 10, by means ofwhich'it can be readily.

clination being indicated by the line all-m in Fig. 1. The block 17 isprovided with a lateral and threaded bore 30 into which is let thethreaded stem 31 "of a set screw 32, which is provided with a collar33'and a flange 34:. The blade 26 is provided with an aperture throughwhich the stem 31 is passed and in which the collar 33 is received, thecollar 33 forming a bearing for pivotally supporting the blade thereon,and the flange 34:, together with the projection 35 on the block 17providing means for confining the v the amount of inclination given itrelative to the plane of the seam of the cigarette rod, cause thepressure of the contact to be a gradually increasing one, and at thesame time afford means for placing upon the blade at the point where theforce of its contact upon the seam'of the cigarette rod is desired to bethe greatest, a variable pressure,

so that the contact of the blade with the seam at its front end will beelastic or yielding, as it will then readily yield to any irregularitiesin the same, and exert a gentle pressure thereon. This is very importantwhen it is borne in mind that the desired action of the presser blade isto measurably pull or draw back the parts of the rod which constitutethe seam, as by the action of the tip of the finger or the nail drawnalong the surface of a piece of paper, at the same time distributing thepaste or other adhesive material, by means of which the lap of the seamis secured together. By the means herein shown, the pivot of the bladeis located adjacent the exit of the cigarette rod from the controllingtube or groove and may be adjusted up or down and retained in thedesired adjusted position so as to secure the desired relative height,and'that the means for regulating the amount of, depression of theblade, for placing upon the seam of the cigarette-rod a yielding orelastic pressure, and for regulating this pressure, are'located rearwardof the pivotal support of the blade and ator adjacent its toe or pointof greatest inclination, to the horizontal.

It will be noted that the device is very simple, avoids the use of heatartificially applied, and may be readily attached to any otherwisesuitably constructed 7 cigarette machine- In Figs. 5 to 12 inclusive, Ihave shown modifications which'embody to a greater or lesser extent theprinciples of construction contained in the device shown in Figs. 1 to 4inclusive. Referring first to Figs. 5, 6 and 7 at 37 is a plate adaptedto be secured to the bed 1 of the machine by a screw 38. The plate hastwo arms 39, 40, the arm 39 being provided with a head 41 which isslotted at 42, into which slot passes the stem of a set screw 43threaded into the head 41, and the arm 40 is provided with a head 44slotted as at 45. Both heads are bored as at 46, in which bore lies aspring 47, and into which bore a set screw 48 is threaded, which bearson top of the spring. The presser blade 26 is not pivoted to either ofthe blocks but is loosely or freely set into their respective slots, asshown in Fig. 5, so that it will bear upon the seam of the cigarette rodby the action of the springs. Either or both of the screws 43, 48 may beadjusted to cause the springs 47 to bear with greater or lesser pressureon the blade and regulate both its height and inclination. The blade isprovided with a lug 49 at the end where it engages with the head 41 andthrough this lug is passed a pin 50, which bears against the sides ofthe head 41. The function of this pin is to prevent the forward movementof the blade in the direction of the movement of the cigarette rod.

In Figs. 8 to 11 inclusive is shown a further modification. In theseviews the presser blade comprises a block 26, which in cross section isin the shape of a truncated pyramid, its operative or contact surface 27(shown diagrammatically in Fig. 11) being substantially of the lateraldimensions of the seam of the cigarette rod. The blade 26 is removablyand detachably secured to the plate 2 by providing the latter with ashort recess 51 (Fig. 8) and the former with a lug or projection 52which is let into the recess, this form of connection being had mainlyfor the purpose of preventing the blade from becoming laterallydisplaced, at the same time providing a movable connection of it withthe supporting blade 2'. At 53 is a flat bow spring having flattenedends 54, 55, the end 54 being screwed to the fiat top 56 of the blade 26adjacent its toeportion 29, the end 55 being provided with a holethrough which is passed the threaded stem 57 of the fastening screw 58,which has a flange 59 bearing on top of the end 55 of the spring, theplate 2 having a tapped hole receiving the threaded stem 57. By means ofthese devices the spring may be readily and detachably secured to theplate 2 or any other desired portion of the machine. The spring 53causes the blade 26 to bear down on the seam with a yielding pressureand gives to it the desired angle of inclination, as indicated by thedotted line ea in Fig. 9. It will be noted that the heel 28 of the bladeis capable of yielding and exerting a relatively light pressure upon theseam of the rod as the latter emerges from the controlling or guidingtube, and that this pressure increases with the amount of pressureexerted by the spring 53, the latter giving the presser blade thedesired amount of downward inclination at the toe portion 29.

In Fig. 12 is shown another modification, in which the presser blade 26is suspended over the plane of the cigarette rod by rods 60 fixed in thebed 1 which pass into guides 61 fixed to the blade, and which hold theblade in its proper position relative to the seam and prevent itslateral displacement, while permitting of its vertical movement. At 62is sectional weight resting upon a shoulder 63 on a rod 64, which issuitably secured to a lug 65 on the blade 26. The weight may be variedlike the conventional weights on a scale. The operative or con tact edge27, in this form of the device, may be parallel with the plane of theseam, but I prefer, in order to realize all the benefits of myinvention, that it be inclined at an angle, as shown by the dotted linecc:c, so that the heel 28 will be higher than the toe 29 and exert uponthe seam a gradually increasing and preferably yielding pressure in thedirection of the length of the seam.

From the foregoing, it will be noted that myinvention may be variouslymodified, without departing from its spirit.

I do not claim, in this application, the specific forms of the devicesshown in Figs. 8 to 12 inclusive as they form the subject matter offurther applications filed by me, said applications having been filed onthe 3rd day of August, 1913, Serial Nos. 782,607 and 782,608.
